Thanks Fred
My first idea come after reading to Robert T. Bakker and Gregory S. Paul several years ago about opened areas for plausible habitat for sauropods, from that initial idea, I decided located them on an habitat similar to grassland, but in jurassic times, ther are not grasses. Probabbly ferns were domiant plants in those times.

Yeah, ferns is what I thought of aswell. Although, the yellow field you did does look like grass :/ I guess you didnt want to get too specific with the detail in that area. Great art man!

Gracias Antonio.
Un gusto verte por aquí. La intención de mi trabajo es mostrar a las especies extintas en sus actividades cotidianas, más o menos como las veríamos si estuvieran en su ambiente natural hoy en día.
Con la limitante de que el registro fósil es frustrantemente escaso cuando se requiere información.

Hi! Paleo-King,
good point, Apatosaurus was more massive and few larger (near 23 mt large) than Brachiosaurus (21 mt large), may be looks bigger because one of them its close at observer and its stand up.
Brachiosaurus was a weight near 31 tons and Apatosaurus 17-18 tons.
Perhaps one can have an approximate idea looking Apatosaurus on herd, behind that stand up one, they are almost at same plane than Brachiosaurus herd, that looks almost at same scale and looks smaller.

Sorry, I think there's some confusion here...

You're saying Apatosaurus was more massive? But then you say it was only 18 tons and Brachiosaurus was 31 tons. Those are two contradictory statements.

Furthermore, the measurements in meters are just length, they have nothing to do with mass or volume - and your estimates are wrong (don't take it personally). Even if a FEW documented Apatosaurus individuals reached 23m (most did not), Brachiosaurus still had far greater mass and volume than Apatosaurus - which is the opposite of what the painting suggests. Furthermore your estimate of 21m for Brachiosaurus is too low. 21m = 69.3 feet, which is actually more like a typical Apatosaurus length. Although Brachiosaurus had a shorter tail, it had a much longer neck and torso and greater overall size, making Brachiosaurus actually longer than most Apatosaurus. The type specimen of Brachiosaurus altithorax was 24m (80 feet long), as it had a longer torso than the similar-sized Berlin Giraffatitan (HMN-SII), which was 23m (75 feet) long. But both of these animals were not fully grown, as their scapulae and coracoids were unfused. In fact, there are even larger Brachiosaurus and Giraffatitan remains known, Brachiosaurus probably reached up to 28m (92 feet) long as an adult (if you cross-scale from the Potter Creek remains and also using the largest Giraffatitan specimen, HMN XV2, as a reference). That's right, Brachiosaurus wasn't 75 feet long as an adult - it was more like 90 feet.

So realistically, the Brachiosaurus in the painting should be about 20-25% larger than they are, or the Apatosaurus should be 20% smaller. The good news it this can be done quite easily digitally, you don't have to go back and mess with the actual painting.

You're correct about one thing though - the Apatosaurus that's in the foreground is closer to the observer than the Brachiosaurus herd, but that doesn't account for its excessive size, and it's not THAT much closer. The Apatosaurus individuals behind it are also too big relative to the Brachiosaurs, despite being farther away, so the only way this scene would make sense is if the brachiosaurs are a subadult herd. We know that this probably isn't a realistic assumption, because all the known trackways of Brachiosaur herds show a mix of different-sized individuals from 2-ton juveniles to huge 40-ton adults. As soon as the babies reached a ton or more, they probably joined up with a mixed-age herd. Beyond that size, they no longer lived in size- or age-segregated herds.

Hi! Brad-ysaurus.

On ground I represented some hypothetical ferns, as you know, grasss apperars on fossil record several millions of year later.
The idea is represent a plant eaters comunity on a open landscape, animals with very big bodies couldnt´live in a dense forest, so, opened areas shouldn´t be "naked", surely some kind of plants occupied the ecological equivalent of actual grass.

Good point. Apatosaurus seems bigger than Brachiosaurus because one of them is up right. Apatosaurus was masive and heavy but Brachiosaurus is taller

Makes sense. I'm just used to ferns being green, are they sometimes yellow too?

Ferns are mainly green, but sometimes can be redish when comes new frondes (leaves of ferns), or brownish when they are dry.
Intermediate color could be possible in intermediate stages
Actual species of ferns are in several forms and color, certainly green is a dominant color of group but also bluish, pale green, dark green, purplish.
About forms, it´s widely oberved the typical form of fronds, but if you seek on ferns group, you´ll find many diferent forms, even some like grass or like vascular plants shapes

Hi Ferahgo,
Thanks for you message, I´m sorry but I miss the idea, What do you mean?

EWilloughby In reply to bioimagen [2011-03-31 01:41:58 +0000 UTC]

Sorry, I was being facetious. Greg Paul has recently gotten angry with people for copying his poses, saying that anyone who draws a side profile of a running dinosaur with its left foot off the ground is using his idea.

It's an absurd notion and I enjoy poking fun at it. Your painting is beautiful and I didn't meant to shift focus from it! Great work.

Hi Ferahgo,
Greg could be right, his influence is notorious and may be his personal seal. I knew about his work both paleontologic and artistic, near 1989-90. I remember that his paticular style is to represent his animals with a hind limd flexed, in many cases on side.
With pass of time, his influence on many of us was very strong. Many people began to represent their animals at Paul´s style, mainly on black and white artwork and sometimes is not possible to identificate the artist.
Later, came "Jurassic park", the theropods in the movie are his animals become to life.
I consider my self like his fan numer one in Mexico, and he know it, I told him when I met him in a SVP in 2000 in Mexico City. It was an unforgatable experience for me to meet one of my most admired people.
I consider too, that each one us should to develop a personal style on artwork. Influences are inevitables, but always with a personal feeling.

Best wishes

Well, that's true of course. Developing a personal style is always very important, and he was very influential on my early style for dinosaurs as well. I think he's currently overreacting about it, but I definitely agree that it's too bad when people copy his style directly, which is a rampant problem in paleoart currently.

Yes, many people copy his style, but form many others paleoartists too, I´m sure you have seen the famous image for book cover "Dinosaurs heressies", Jonh Gurche is other victim of copies at great scale
